Remove solutions from forum hint articles?

Edited by @moT01:

I hope you don’t mind @qaz6209031, but I am changing this issue to discuss the removal of the solutions in the hints. I fixed the original issue described below, see the conversation for the new direction of the issue.

Describe your problem and how to reproduce it:

There are several bugs in freeCodeCamp Challenge Guide: Timestamp Microservice Solutions section All these bugs can be reproduced by submiting the timestamp project with the solution in the hint

This first bug is a typo

 if (dateObject.toString() === "Invalid Date") {
    res.json({ error: "Invaid Date" });
 }

res.json({ error: "Invaid Date" }) should change to res.json({ error: "Invalid Date" })

The second bug is

if (/\d{5,}/.test(dateString)) {
    dateInt = parseInt(dateString);
    //Date regards numbers as unix timestamps, strings are processed differently
    res.json({ unix: dateString, utc: new Date(dateInt).toUTCString() });
}

The res.json({ unix: dateString, utc: new Date(dateInt).toUTCString() }); } should change to res.json({ unix: dateInt, utc: new Date(dateInt).toUTCString() }); } since unix field is expecting a number not a string

The third bug is a runtime error Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client, I think the original solution is calling res.json() twice if we do a get request on projecturl/api/timestamp/1451001600000 So the simplest way to fix this in my opinion is just add a else condition like the following

if (/\d{5,}/.test(dateString)) {
    dateInt = parseInt(dateString);
    //Date regards numbers as unix timestamps, strings are processed differently
    res.json({ unix: dateInt, utc: new Date(dateInt).toUTCString() });
} else {
    let dateObject = new Date(dateString);

    if (dateObject.toString() === "Invalid Date") {
      res.json({ error: "Invalid Date" });
    } else {
      res.json({ unix: dateObject.valueOf(), utc: dateObject.toUTCString() });
    }
}

Thank you, @ieahleen. I was actually waiting for someone to assign me the issue. Now I understand. I will go through the contributing docs and also submit the PR.
